OBJECTIVE Magnetic resonance findings with clinical and arthroscopic correlation of intraligamentous cysts of the anterior cruciate ligament (ACL) are presented. MATERIALS AND METHODS Three cases of intraligamentous cysts of the ACL were identified out of 681 knee MRI examinations over a 2-year period. Arthroscopy and postoperative MRI were performed in(More)
AIM To investigate changes on magnetic resonance imaging (MRI) which occur with intracavitary Gliadel wafer placement in patients with glioblastoma multiforme (GBM). METHODS This retrospective Health Insurance Portability and Accountability Act-compliant study was approved by the institutional review board, with a waiver of informed consent. A total of(More)
OBJECT Few data are available on how closely stents appose the luminal vessel wall in stent-mediated coil embolization of intracranial aneurysms and on the effect of incomplete stent apposition on procedural thromboembolic complications. METHODS Postprocedural 3-T MR diffusion-weighted imaging and time-of-flight angiography were obtained in 58 patients(More)
The purpose of this study was to analyze the CSF flow in patients with Chiari I to determine differences between patients with and without CAH. Thirty patients with Chiari I malformation underwent cine-PC CSF flow imaging in the sagittal plane. CSF flow pulsations were analyzed by placing regions of interest in the anterior cervical subarachnoid space.(More)
OBJECTIVE We describe an inexpensive and simple method for optimal visualization of the hip with MRI. MATERIALS AND METHODS A flexible shoulder surface coil and off-coronal planes of section oriented parallel to the long axis of the femoral neck are used for MR studies of the affected hip. RESULTS From January 1993 through December 1993, 155 hip MR(More)
Magnetic resonance imaging is the current imaging modality of choice in the evaluation of patients presenting with myelopathic symptoms in the search for spinal cord lesions. It is important for the radiologist to recognize and differentiate nonneoplastic from the neoplastic process of the spinal cord as the differentiation of the 2 entities is extremely(More)
A tricomponent coaxial system (TAS) suitable for colonic decompression with fluoroscopic guidance is described. The TAS was successfully used in four of four patients, two with acute pseudo-obstruction, one with sigmoid volvulus, and one with recurrent colonic pseudo-obstruction. All patients had acute abdominal distention with cecal diameter of at least 12(More)
OBJECTIVES Identification of the targets of radiation damage after radiosurgical treatment of ocular melanoma will potentially allow for sparing of vision with improved treatment planning. MATERIALS AND METHODS Six patients with ocular melanoma, who had useful vision before therapy, were treated with gamma knife stereotactic radiosurgery with curative(More)
